Police investigating the murder of Auckland teenager Jane Furlong have spent the weekend excavating a patch of ground next to the block of flats where she was living when she went missing in 1993.
Ms Furlong was just 17 when she disappeared from Auckland's Karangahape Rd while working as a prostitute. Her remains were found in a sandy grave at Sunset Beach near Port Waikato two months ago.
A blue tarpaulin has been erected next to the carport of a quiet block of five flats on Heretaunga Ave, Onehunga.
A generator could be heard working inside as Environmental Science and Research staff in overalls carried out containers filled with soil and rock.
Neighbours said police had been in and out of the property since Friday, sifting through piles of dirt.
